FLY-NET PUNCH.

SPECIFICATION forming part of Letters Patent No. 247,971, dated October 4, 1881.

Application filed May 25, 1881. (No model.)

To all whom it may concern Be it known that 1, WILLIAM E. VARNEY, of Daytonville, in the county of Washington and State of Iowa,have invented an Improved Fly-Net-Bar Punch, of which the following is a specification.

The object of this invention is, to provide a machine for punchin g holes for the net-strands in the leather bars or straps more rapidly and accurately than is now done and without removing any of the leather.

Figure l is a partly-"sectional front elevation of the device 011 line 00 m, Fig. 2. Fig. 2 is a sectional end elevation on line y y, Fig, 1. Fig. 3 is a sectional elevation of a portion of the device on line 2 2, Fig. 1.

Similar letters of reference indicate correspending parts.

' or punch shaft E, which latter carries on its lower end the two-pronged fork or punch E.

A guide-frame, F, attached to the standard A serves to support or hold in a vertical position the fork or punch shaft E, that passes through it. A presscnfoot, G, also has its shank G held in the guide-frame F, parallel with the punchshaft E, and, within said frame F, is encircled by a spiral spring, G to keep said foot Gr pressed down on its work. Said presser-foot G may be raised at any time by turning a handled'eecentric, H, that is pivoted on the frame F against a stud, a, that projects from the said presser-foot shank G.

The strap or bar I that is to be operated upon is placed on the table A, between the parallel-guides K,-which are secured on said table A by screws or studs 1), that are passedthrough their slotted ears 0, and said guides K are then adjusted to the Width of the said strap or bar 1 by means of a right-and-left screw, L, that passes through the lugs 01 of the guides K, which depend below the top of said table A, as shown in Fig. 1. The strap or bar I is extended along beneath the punch E and presser-foot G,'and is pressed by the latter upon the feed spur-wheel M, whose periphery extends slightly up through a corresponding opening in saidtable A. Said feed-wheel M is keyed on one end of a shaft, M, that is journaled in suitable hangers,f, depending from the under side of the table A, and said shaft M has secured on its opposite end a ratchet-wheel, O, that is inclosed in a flanged wheel, P, which is loosely secured on the extreme outer end of said shaft M. Within this wheel P is' pivoted a pawl or dog, h, that is designed to engage in the teeth of the ratchetwheel 0 intermittently when the machine is in operation, in order to thereby move the feedwheel M to advance the strap or bar I as required beneath the punch E. This wheel P is connected with the fly-wheel Q on the shaft 0 by means of an eccentric-rod, P, in such a manner that when the machine is in operation a short rocking motion is given to the wheel P, and thence, by means of the dog It and ratchet O, to the shaftM. As the strap or barIis fed along by the feed-wheel M the punch E is moved up and down, and at each downward stroke its points are driven through said strap or bar I, thereby forming, without removing any of the leather, the holes for the nettingstrands. The rate of feed of the said strap or bar I may be changed at any time by changing the point of attachment of the eccentric-rod P with the fly-wheel Q.

With this machine the work of preparing the straps or bars for fly-netting for horses, &c., is performed with great economy of time and labor.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-
